HTML & XML share the same settings for “Expires header lifetime:”, under Browser cache. We have set it to an hour which is fine for pages, but we would like our RSS feeds to update more frequently. Is there a way to overwrite this setting? programmatically maybe?
In this example, the XML file’s expiration would be set to Access plus 5 minutes (300 seconds). Be careful if you copy-and-paste that, sometimes the < and > characters don’t come through in the forum well, so double-check that they are carets and not & characters.
